FRITZ MINK, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE KEYSTONEWATCH CASE COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OFPENNSYLVANIA.

wAroHoAsE.

To all whom it may concern:

Be it known that I, FRITZ MINK, a citizen of the UnitedStates, and aresident of Philadelphia, in the county of Philadelphia and State ofPennsylvania, have made and invented certain new and useful Improvementsin lVatclicases, of which the follov ing is a specification.

My invention relates to an improvement in the construction of watchcases, and more particularly to that part or parts thereof usually knownand referred to as the pendant and bow the object of the same being toprovide such an attachment for the two parts that the bow will beallowed a swivel or free movement upon the pendant, and wit-hout dangerof it being accidentally disengaged therefrom, or purposely twisted fromits position by thieves and pickpockets, as can be done in the usualform of bows and pendants, wherein the ends of the latter are simplysprung into recesses provided in the former.

A further object of my invention is to produce a pendant and bow whichmay be easily and readily assembled, and which will lend to the finishedarticle a neat and attractive appearance, and with these and other endsin view, the invention consists in certain novel features ofconstruction as will be hereinafter fully described and pointed out inthe claims.

In the accompanying drawings, Figure 1 is a view partly in elevation andpartly in section of a pendant and bow constructed and assembled inaccordance with my invention. Fig. 2 is a similar view of a modificationthereof. Figs. 3, 4 and 5 are views of a part of a pendant and bow,constructed in accordance with my invention and shown partly in sectionand partlyT in elevation, the crown of the watch being omitted.

Referring to the drawings, 6 represent-s a watch bow of that type orstyle usually known and referred to by the trade as a French or Swissbow, by reason of its shape and the provision on the ends thereof of theprojections 7, this bow being commonly used or employed in connectionwith an antique pendant, comprising the boat or body 8 of somewhat ovalform, and the neck 9, the latter being soldered or otherwise secured tothe watch case 10.

The object of my invention is to securely fasten the ends of a Swiss bowto an antique Specification of Letters Patent.

pendant in such a way or manner thatthe bow will be free to movethereon, and at the sam-e time securely fastened in position. For thispurpose, I construct the ends of the oval 8 of the pendant in somewhatconical form, as illustrated at 11, a groove or recess 12 being formedin the oval somewhat back of the eXtreme end thereof, to form aconstricted neck. In each of the ends 7 of the bow G, I provide aconical recess 13 adapted to receive and nicely contain theconical-shaped end of the oval 8, the two parts, that is, the ends ofthe oval 8 and the ends of the bow G, being thus centered, and while thebow is thus permitted to have a free swivel or movement on the pendant,all play or movement thereof in a horizontal plane is avoided. The ends7 are each provided with the restricted neck 14, similar to that formedon the ends of the oval 8, the restriction in each instance being due tothe removal of the metal from the respective parts, or due to theenlargement of the ends of the oval and bow. Around these ends of theoval and bow, formed and assembled as above described, are fitted thesleeves 15, somewhat spherical in form, the edges or ends of which arespun, bent or burnished over to fit into the restrictions 12 formed inthe oval, and 111 formed in the bow, these sleeves securely and tightlyholding the bow and pendant in their proper relative positions, and atthe same time allowing the proper movement of the bow with relation tothe pendant.

In Fig. 2 I have shown practically the same construction as thatillustrated in Fig. 1, the difference being that the conical recess 20is formed in the oval, and the conical end 21 on the end of the bow, thereverse of that shown in Fig. 1. In these two figures 1 and 2, it willbe seen that the interlocking ends of the oval and bow are somewhatenlarged, but it will be understood by those skilled in the art, thatsuch is not absolutely essential. In Fig. 3, for instance, I have shownthe inner end 22 of the bow G, in which is formed the conical recess, asbeing of the same size as the outer end 23, the conical-shaped end 211of the oval 8 being of a corresponding size. In this structure, as inthe two preceding structures, a sleeve 25 will be employed for retainingthe parts in their proper relative positions.

In Figs. 4 and 5, I have shown further modications of my invention,wherein each end of the bow 28 is provided with the ball or knob 26formed on the inner end of the pin 27, this pin extending through theend of the bow, and its outer end slightly headed over to prevent itsremoval therefrom. This end 26 may be contained within a recess formedin the oval 29, as illustrated in Fig. 4, or may be secured to the oval30 by means of the sleeve 31, as illustrated in Fig. 5, said sleeve 31being secured in position, and operating to eiiect the same results inthe case of the structures illustrated in Figs. l, 2 and 3.

From the foregoing it will be understood that in each instance the bowis permitted a rocking movement with relation to the pendant, while atthe same time all lateral play, which might be caused or produced by atwisting movement, is avoided. Furthermore, the employment of the sleevebetween the bow and the pendant adds materially to the neat appearanceand esthetic eifect of the antique pendant and bow, it being difficultto determine, when the parts are nicely made and assembled, whether th-esleeve, in the form oi a knob or ball, is not made integral with one ofthe parts, that is, with the bow or pendant, without a close examinationthereof. Particularly is the effect a pleasing one, when the sleeve isused in connection with a French or Swiss bow, wherein the outer extremeend projects beyond the oval portion of the bow.

That I claim is 1. rlhe combination with an antique pendant comprisingon oval and neck, or' a bow engaging with the extreme ends of said oval,and a sleeve fitting around the ends of said oval and bow for holdingthe parts in their proper relative positions.

2. The combination with an antique pendant comprising an oval and neck,of a bow, the end of one of said parts being conical shape and fittinginto a conical recess formed in the other of said parts, and a sleeveiitting over the engaging ends of said parts to hold the same in theirproper relative positions.

3. The combination with an antique pendant comprising an oval and neck,the extreme ends of said oval being conical shape and provided with arecess, oi2 a bow, the ends of which are provided with conical recessesto receive the ends of said oval, and sleeves adapted to fit over thesaid ends to hold the parts in their proper relative positions,substantially as described.

Ll. The combination with an antique pendant comprising an oval and neck,the eX- treme ends of said oval being enlarged and of conical shape, andprovided with a rev cess, of a French bow, the inner ends oi which areenlarged and provided with conical recesses to receive the enlarged endsof said oval, and each provided with a recess, and sleeves adapted tofit over said ends and in said recesses, whereby to hold the severalparts in their proper relative positions, substantially as described.

Signed at Philadelphia, in the county ot' Philadelphia and State ofPennsylvania, this 8th day of May, A. D. 1911.
